Can we have a rule against posting personal anecdotes about a support experience?

Every post about a company's support just devolves into people trotting out a single experience as evidence in favour of or against the company. It doesn't matter how good or bad a company's customer support is, there's still going to be people with good and bad opinions of it.

All customer support requests are different and saying you had no problem returning a laptop doesn't mean someone else won't.
